Procedures

A scale drawing of a garden uses scale 1 cm : 6 m. The drawing
shows the garden as a rectangle 3 cm by 2 cm. What is the actual
area of the garden?

216 m^2 (compute actual dimensions first, then multiply)

36 m^2 (multiply drawing area 6 cm^2 by the scale factor 6)

12 m^2 (same as the drawing area, just relabeled)

108 m^2 (multiply drawing area 6 cm^2 by 18)
